Can a Concussion Cause POTS? Understanding Post-Concussion Autonomic Dysfunction

Concussions are commonly associated with symptoms such as headaches, dizziness, and difficulty concentrating. However, many patients experience symptoms that persist long after the initial injury. One possible explanation for these lingering symptoms is autonomic nervous system dysfunction, including Postural Orthostatic Tachycardia Syndrome (POTS).

At Nova Neuro Brain Center in Chantilly, Virginia, our team evaluates patients with persistent post-concussion symptoms to determine whether conditions such as POTS may be contributing to their recovery challenges.

Understanding the connection between concussion and POTS can help patients seek appropriate evaluation and treatment sooner.

Can Someone Develop POTS from a Concussion?

Yes. Research suggests that POTS or POTS-like symptoms may develop after a concussion or mild traumatic brain injury (mTBI).

The autonomic nervous system regulates many automatic functions in the body, including:

Heart rate
Blood pressure
Blood circulation
Breathing patterns
Digestive function

After a concussion, the brain areas responsible for autonomic regulation—particularly the brainstem and associated neural pathways—may become dysregulated.

This disruption can lead to orthostatic intolerance, a condition where the body struggles to regulate blood flow when changing positions, such as moving from lying down to standing.

In some patients, this dysfunction can develop into Postural Orthostatic Tachycardia Syndrome (POTS).

Symptoms of POTS After a Concussion

Patients with post-concussion autonomic dysfunction may experience symptoms including:

Rapid heart rate when standing
Dizziness or lightheadedness
Fatigue or exercise intolerance
Brain fog or difficulty concentrating
Headaches
Shortness of breath
Palpitations
Weakness or near fainting

Because many of these symptoms overlap with post-concussion syndrome, autonomic dysfunction may sometimes go undiagnosed without specialized testing.

Research Linking Concussion and POTS

Emerging research has highlighted the connection between traumatic brain injury and autonomic dysfunction.

A study published in the Journal of Neurologic Physical Therapy reported that 11.4% of patients diagnosed with POTS experienced symptom onset within three months of a concussion.

Another study published in Cardiology Journal documented cases where patients developed Postural Orthostatic Tachycardia Syndrome following traumatic brain injury, indicating that neurological injury can contribute to autonomic dysfunction.

These findings suggest that clinicians should consider autonomic nervous system evaluation in patients with persistent concussion symptoms.

How Is POTS Evaluated After a Concussion?

Tilt Table Evaluation

One of the primary diagnostic tools for POTS is a tilt table test, which evaluates how the body responds to changes in position.

During this evaluation:

The patient lies flat on a specialized table.
The table gradually tilts into an upright position.
Heart rate and blood pressure are continuously monitored.

A heart rate increase of 30 beats per minute or greater within 10 minutes of standing may indicate POTS.

Tilt table testing can help determine whether symptoms such as dizziness, fatigue, or exercise intolerance are related to autonomic nervous system dysfunction.

What Is the Recovery Time for POTS After a Concussion?

Recovery timelines vary depending on the severity of autonomic dysfunction and the treatment approach.

Typical recovery patterns may include:

Weeks to months
Mild autonomic dysfunction may improve with appropriate rehabilitation and lifestyle adjustments.

Several months to one year
Patients with persistent post-concussion syndrome and autonomic dysregulation may require structured neurological rehabilitation programs.

Longer-term management
Some individuals benefit from ongoing autonomic conditioning and physical therapy.

Early identification and treatment significantly improve recovery outcomes.

Current Treatment Approaches for POTS

Standard medical management may include:

Salt tablets to increase blood volume
Increased fluid intake
Compression garments
Medications when appropriate
Physical therapy rehabilitation programs

Increasing salt and fluid intake helps maintain circulating blood volume and reduce symptoms related to orthostatic intolerance.

However, many patients benefit from comprehensive neurological rehabilitation that addresses the underlying autonomic dysregulation.

Nova Neuro Brain Center’s Approach to Treating POTS After Concussion

At Nova Neuro Brain Center, our treatment programs focus on restoring proper communication between the brain and autonomic nervous system.

Our comprehensive approach may include multiple therapies designed to support neurological recovery.

Tilt Table Rehabilitation

Tilt table therapy can be used to gradually retrain the autonomic nervous system to tolerate upright positioning.

This progressive exposure helps improve regulation of heart rate and blood pressure.

Graded Physical Therapy Program

Patients participate in a structured graded exercise program designed to improve cardiovascular regulation.

Programs often begin with low-intensity or recumbent exercises and progress gradually as tolerance improves.

Nervous System Rehabilitation

Our neurological rehabilitation therapies focus on restoring brain-body communication through targeted exercises and neuroplasticity-based interventions.

Therapies may include:

Neurological rehabilitation exercises
Brain-body integration therapy
Balance and coordination training

Vagus Nerve Rehabilitation

The vagus nerve plays an important role in autonomic nervous system regulation.

Therapies that support vagal tone may include:

Breathing exercises
Parasympathetic activation techniques
Neuromodulation therapies

Comprehensive Concussion Rehabilitation

Additional therapies may include:

Vestibular therapy
Vision therapy
Cognitive rehabilitation
Neuromotor training
Autonomic nervous system retraining

By addressing both concussion recovery and autonomic dysfunction, patients often experience meaningful improvements in symptoms and overall function.

When to Seek Evaluation for POTS After a Concussion

If you have experienced a concussion and continue to have symptoms such as:

dizziness when standing
rapid heart rate
fatigue
exercise intolerance
persistent brain fog

you may benefit from a comprehensive neurological evaluation to assess for autonomic dysfunction.
